Active vibration dampers have been gradually used because they have the advantages of reducing the vibration drastically and adaptively. However, one main drawback is the requirement of large amount of energy. Vibration itself is one type of energy and an actuator is an energy converter, so the question arises as to how we can utilize this energy. This paper describes an energy -regenerative-type vibration damper. In this study, electric power is regenerated during high-speed motion of the actuator. For low-speed motion, an active or passive control algorithm is applied to the same actuator to achieve good damping performance. This method is applied to a single degree-of-freedom vibrating system with a linear DC motor. The system is simulated on a computer and a simple experiment is performed. The results show that the proposed system performs better than purely passive vibration control and can regenerate vibration energy.
